TL;DR: In this article, a detailed analysis of the thermal expansion mechanism of graphite oxide to produce functionalized graphene sheets is provided, where it is shown that the decomposition rate of the epoxy and hydroxyl sites exceeds the diffusion rate of evolved gases, yielding pressures that exceed the van der Waals forces holding the graphene sheets together.

TL;DR: In this paper, an alumina ceramic 12.5×12.0 mm micro-reactor was constructed using a modified stereolith-ography process to facilitate a high level of heat transfer between reactants and combustion products and wall surface contact of the flow through the microreactor body.

TL;DR: In this article, the authors report a comprehensive polarized and unpolarized neutron scattering study of the evolution of the dynamical spin susceptibility with temperature and doping in three underdoped single crystals of the YBCO{6+x} high temperature superconductor.

TL;DR: Polarized and unpolarized neutron scattering have been used to determine the effect of superconductivity on the magnetic excitation spectra of YB${\mathrm{a}}_{2}$C${{O}}_{6.5}$ $({T}_{c}\phantom{\rule{0ex}{0ex}}=\phantom{rule{ 0ex}{ 0ex}}67\phantastic{\rule}0ex})$ as discussed by the authors.

TL;DR: An absolute intensity scale for the dynamical spin susceptibility is established by calibrating the measured magnetic intensity against calculated structure factors of optical phonons and against antiferromagnetic spin waves measured in the same crystal after deoxygenation to YBa{sub 2}Cu{sub 3}O{sub 6.2}.
